Rifle Combat Magwell for AR-15 MILSPEC Forged Lowers

The RCM (Rifle Combat Magwell) is designed for AR-15 MILSPEC forged lower receivers and features an optimal 175% increase in flared funnel surface area allowing for consistent and fast reloads under any condition while maintaining a slim overall profile. Updated for 2026 with an improved injection-molded polymer material and design.

Compatible with all major magazines (including M3 PMAGs) on the market as well as higher capacity options like the Magpul D60 or Surefire MAG5-60.

The RCM works great for unconventional shooting positions, working under night vision or reloading on the go. With the RCM you focus less on getting rounds in the gun and more on getting them down range.
